A group of Democratic attorneys general who promised to work together to fight climate change may be trying to avoid public scrutiny of that work.

The Energy and Environment Legal Institute released an agreement among 17 Democratic attorneys general, led by New York Attorney General Eric Schneiderman, that the right-leaning think tank says is trying to skirt public records laws.

The common interest agreement signed by all the attorneys general included a provision making all documents regarding the climate pledge to be marked confidential. That would keep all of those documents blocked from any Freedom of Information Act requests.
